Chemistry

7 0

Explanation:

A chemical reaction in which heat energy is absorbed by the reactant molecules is known as an endothermic reaction.  

For example, A + B + Heat \rightarrow AB

The value of \Delta H = +ve for endothermic reaction.

Whereas a chemical reaction in which heat energy is released by the reactant molecules is known as an exothermic reaction.  

For example, C + D \rightarrow CD + Heat is an exothermic reaction.

The value of \Delta H = -ve for exothermic reaction.

Also, the given reaction, 2C_{2}H_{4}O(g) + 5O_{2}(g) \rightarrow 4CO_{2}(g) + 4H2O(l)          \Delta H = -2385 kJ

It is also an exothermic reaction because heat is releasing as value of \Delta H is negative.

Thus, we can conclude that the given reaction is exothermic in nature.

Particle size directly affects which of the following spil properties?
77julia77 [94]

Answer:

The size of soil particles is important. The amount of open space between the particles influences how easily water moves through a soil and how much water the soil will hold. Too much clay, in proportion to silt and sand, causes a soil to take in water very slowly. Such a soil gives up its water to plants slowly.

3. 25. The temperatures favorable for the growth of most bacteria are
kvasek [131]

B.

about the same as for humans

Explanation:

This is why most bacteria, during research in labs, are incubated at 37 degrees centigrade, about the same as human body temperature. In addition, harmful and beneficial bacteria thrive in the human body due to the favorable temperatures for growth and reproduction. To try and fight an infection, the body also tries to raise the body temperatures above the optimal for the bacteria  growth (the reason one has a fever in case of infection).

If one mole of a substance has a mass of 56.0 g, what is the mass of 11 nanomoles of the substance? Express your answer in nanog
9966 [12]

Answer:

616,0 ng is the right answer.

Explanation:

You should know that 1 mole = 1 .10^9 nanomoles

Get the rule of three.

1 .10^9 nanomoles ...................... 56.0 gr

11 nanomoles .....................

(11 x 56) / 1 .10^9 nanomoles = 6.16 x 10^-7 gr

Let's convert

6.16 x 10^-7 gr x 1 .10^9 = 616 ngr
